Answer:
Z-score = -1.285
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 17.6 seconds
Standard Deviation, σ = 2.1 seconds
Formula:
For x = 14.9, we have:
A z-score to be unusual if its z-score is less than -2.00 or greater than 2.00.
Thus, the z-score is not unusual as it lies in the range [-2.00, 2.00]
The answer is the third option (2 square root 22)
Applying probability concepts, it is found that the correct statements are:
- c) pa and pb are not equal
- d) pa is 2/3 and pb is 1/3
-------------------------------------------
- A probability is the number of desired outcomes divided by the number of total outcomes.
The sample space, that is, the possible outcomes for the coin tosses is given next, considering H for heads and T for tails.
H - H
H - T
T - H
T - T
-------------------------------------------
- Considering that there is at least 1 tails, the new sample space is:
H - T
T - H
T - T
- pa: probability of one head, two outcomes with 1 head out of three, thus, pa = 2/3.
- pb: probability that the second is tails, so one outcome(T - T) out of three, thus pb = 1/3.
-------------------------------------------
The correct statements are:
- c) pa and pb are not equal
- d) pa is 2/3 and pb is 1/3

Answer:
3 is your answer im pretty sure:)))
Step-by-step explanation:
Answer:
The rate of change is 6.
Step-by-step explanation:
Using the point slope form we know that y-y1/x-x1
so 12-6/2-1
this gives 6/1 which is 6.
